The default bindings map the left and right mouse buttons to Square and
R2, and mouse mode maps motion to the right stick. A title that opens the
mouse with sceMouseOpen therefore gets every click twice: as a mouse
button and as a pad press. PPSA15388 treats the pad press as a switch to
gamepad input, re-centres its cursor and drops the click, so menu items
cannot be clicked.
While libSceMouse has a handle open, KeyboardMouse ignores mouse motion
and mouse-button presses. Releases still pass, so a button held before
the title opened the mouse is let go. Keys and the wheel are unchanged,
as with the IME guard next to it.
